Description

Technical Field

[0001] The invention relates to the technical field of pipeline through-hole processing, in particular to a universal rubber-lined pipeline through-hole processing device for machine tools. Background Art

[0002] Rubber-lined pipe is a special piping system whose main feature is that the inner wall of the pipe is lined with one or more layers of rubber material. This design is intended to improve the corrosion resistance, wear resistance and sealing of the pipe. The rubber lining can adapt to different working environments, including extreme conditions such as chemical corrosion, high temperature, low temperature and high pressure. These pipes are widely used in chemical, petroleum, food, medicine, water treatment and other industries to transport various media. By coating the inner surface of metal or other base material pipes with rubber, rubber-lined pipes not only enhance the service life of the pipes, but also provide good chemical resistance and impact resistance.

[0003] The rubber-lined pipe through-hole processing equipment fixes the rubber-lined pipe to be processed on the machine tool to ensure its stability, and adjusts the position and parameters of the drill bit, such as rotation speed, feed speed and pressure, according to design requirements. The equipment is started, and the drill bit begins to drill holes on the pipe surface under power drive. After the processing is completed, the equipment is stopped, the drill bit is removed, and the size and position of the hole are checked to see if they meet the specification requirements, thereby ensuring the accuracy of the rubber-lined pipe through-hole processing.

[0004] There are still inconveniences in the use of current equipment: the through-hole processing of rubber-lined pipes usually requires extremely high precision for subsequent assembly and use, and the drill bit needs to be at the same height as the pipe axis before drilling. Due to different pipe sizes, the height of the drill bit needs to be adjusted frequently. The process is cumbersome and the manual adjustment accuracy is not high, which causes the drill bit to not be aligned with the pipe axis, and the drilled hole will deviate from the predetermined position, resulting in inaccurate hole position, affecting the subsequent assembly and use of the pipeline.

[0018] Beneficial effects

[0019] The universal rubber-lined pipe through-hole processing equipment for machine tools provided by the present invention has the following beneficial effects:

[0020] 1. Through the coordinated use of the rubber-lined pipe and the movable clamp, when the height of the punching drill bit needs to be adjusted to meet the height requirements of the drill bit and the pipe axis, the rubber-lined pipe is completely clamped by two pushing slides. At this time, the adjustment slide is located at the axis of the rubber-lined pipe. During this process, the punching drill bit is driven to slide inside the outer frame through the connecting mechanism, thereby realizing the alignment of the punching drill bit and the axis of the rubber-lined pipe. Therefore, ensuring the alignment of the drill bit and the pipe axis can ensure the accuracy of the hole position, reduce processing errors, and improve product quality.

[0021] 2. By pushing the slide plate and the fan together, the fan is driven to rotate through the transmission mechanism, and the airflow flows inside the ventilation slot, thereby forming a negative pressure inside the collection box, thereby sucking the dust inside the connecting pipe into the collection box for centralized collection. Centralized dust collection can significantly reduce the dust in the working area, improve the breathing environment of the operator, and prevent dust and fine particles from entering the equipment, causing equipment wear, failure or reduced accuracy.

[0022] 3. Through the coordinated use of the collection box and the collision rod, as more and more dust falls into the movable box, the surface pushes the rod to drive the No. 2 gear to rotate. Since the contact plate extends to the inside of the adjacent tooth block on the surface of the No. 2 gear, the No. 2 gear rotates and drives the collision rod to swing back and forth under the action of the thrust given to the contact plate surface and the collision rod's own gravity, thereby repeatedly colliding with the bell, thereby sounding an alarm to remind the operator to clean the dust collector in time to avoid excessive dust affecting the performance of the equipment and causing dust backflow, which helps to keep the equipment clean and operating normally, thereby extending the service life of the equipment.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] refer to Figures 1 to 7 According to a preferred embodiment of the present invention, a universal rubber-lined pipe through-hole processing equipment for machine tools will be described in detail below. A universal rubber-lined pipe through-hole processing equipment for machine tools includes a universal machine tool 1. A rubber-lined pipe 2 is provided on the surface of the universal machine tool 1. An outer frame 3 is movably connected to one side of the universal machine tool 1. An electric slide rail is provided between the outer frame 3 and the side wall of the machine tool 1. The electric slide rail drives the outer frame 3 to move on the surface of the machine tool 1. A punching drill bit 4 is provided on the inner wall of the outer frame 3. The punching drill bit 4 is attached with any driving member or combination thereof that can be understood by technicians in this field, such as a motor, so it will not be described in detail here. A movable fixture 513 for positioning the axis of the rubber-lined pipe 2 is provided inside the outer frame 3. An adjusting slide 511 and a pushing slide 512 for adjusting the position of the punching drill bit 4 are provided inside the outer frame 3.

[0034] The outer frame 3 is provided with a dust collecting frame 611 to prevent dust from flying, and a collection box 615 for collecting dust is provided inside the outer frame 3. The outer frame 3 is provided with a fan 613 and a movable push block 617 to collect dust into the collection box 615 through negative pressure.

[0035] A movable box 712 for checking the weight of dust inside the collection box 615 is provided inside the outer frame 3 .

[0036] like Figure 2 The outer adjustment slide 511 is slidably connected to the inner part of the outer frame 3, the movable clamp 513 is movably connected to one side of the outer frame 3, the movable clamp 513 is slidably connected to the inner part of the adjustment slide 511, and the surface of the movable clamp 513 is provided with an adjustment groove 515, such as Figure 5The movable clamp 513 is provided with a central push shaft 514 on one end surface, and the central push shaft 514 is slidably connected to the inside of the adjustment groove 515 on the surface of the movable clamp 513. When the height of the drill bit and the pipeline axis is equal, the height of the drilling drill bit 4 needs to be adjusted. An electric telescopic rod is provided inside the outer frame 3, which pushes the movable clamp 513 to slide through the movable rod, and then the two movable clamps 513 are given a force toward the center of the adjustment slide 511 through the central push shaft 514. When one of the two movable clamps 513 first contacts the surface of the rubber-lined pipe 2, the movable clamp 513 that contacts the rubber-lined pipe 2 first cannot slide. The sliding plate 512 is moved, thereby transmitting the force to the surface of the adjusting sliding plate 511 by pushing the sliding plate 512, thereby driving the adjusting sliding plate 511 to slide toward the movable clamp 513 that first contacts the rubber lined pipe 2, until the two pushing sliding plates 512 completely clamp the rubber lined pipe 2. At this time, the adjusting sliding plate 511 is located at the axis of the rubber lined pipe 2. During this process, the punching drill bit 4 is driven to slide inside the outer frame 3 through the connecting mechanism, thereby realizing the alignment of the punching drill bit 4 with the axis of the rubber lined pipe 2, thereby ensuring that the drill bit is aligned with the axis of the pipe, which can ensure the accuracy of the hole position, reduce processing errors, and improve product quality.

[0037] like Figure 4 In the figure, a movable push block 617 is provided on the surface of the push slide 512, and a movable gear rod 612 and a fixed block 618 are provided inside the sliding path of the movable push block 617. The movable gear rod 612 and the fixed block 618 are not located in the same horizontal plane, and a first gear 614 is provided inside the outer frame 3. The first gear 614 is meshed with the movable gear rod 612. Figure 6In the embodiment, the collecting box 615 is arranged inside the outer frame 3, the dust collection frame 611 is slidably connected to the surface of the punching drill bit 4, a connecting pipe 616 is provided between the dust collection frame 611 and the collecting box 615, the fan 613 is connected to the No. 1 gear 614 through a transmission mechanism, a ventilation slot is provided between the fan 613 and the collecting box 615, the surface of the punching drill bit 4 is provided with a dust outlet slot, and the dust outlet slot on the surface of the punching drill bit 4 is connected to the connecting pipe 616, and the surface of one end of the dust collection frame 611 is set to be arc-shaped. As the sliding plate 512 is pushed and driven by the telescopic rod to slide in the direction of the punching drill bit 4, the movable gear rod 612 is driven to slide synchronously. When the punching drill bit 4 is aligned, the punching drill bit 4 is driven by the telescopic rod to drill a hole in the surface of the rubber lined pipe 2. At this time, the dust collection frame 611 is in contact with the surface of the rubber lined pipe 2, and the drilling The dust discharged is guided to the inside of the connecting pipe 616 through the dust suction frame 611 along the dust outlet groove. At the same time, the sliding plate 512 is pushed to contact the inclined surface of the fixed block 618, thereby contracting. At this time, the movable gear rod 612 loses the limit of the movable push block 617, and slides in the direction away from the drilling drill bit 4 under the action of the spring, thereby driving the No. 1 gear 614 to rotate, and driving the fan 613 to rotate through the transmission mechanism, and the air flow flows inside the ventilation groove, thereby forming a negative pressure inside the collection box 615, thereby sucking the dust inside the connecting pipe 616 into the collection box 615 for centralized collection. Centralized dust collection can significantly reduce the dust in the working area, improve the breathing environment of the operator, and prevent dust and fine particles from entering the equipment, causing equipment wear, failure or reduced accuracy.

[0038] like Figure 7 In the embodiment, the movable box 712 is slidably connected to the inside of the collection box 615. A connecting slide shaft 713 is provided on the surface of the movable box 712. The connecting slide shaft 713 slides with the surface of the collection box 615. A power gear rod 714 is provided in the sliding path of the connecting slide shaft 713. A rebound block 716 is provided in the sliding path of the power gear rod 714. The rebound block 716 and the connecting slide shaft 713 are not located in the same horizontal plane. A No. 1 spring 715 is provided at one end of the power gear rod 714. A No. 3 gear 7112 is provided inside the outer frame 3. The No. 3 gear 7112 is meshed with the power gear rod 714. A No. 2 gear is provided on the surface of the No. 3 gear 7112. 717, the surface of the third gear 7112 is provided with a push rod 718 and a rebound pick 719. As more and more dust falls into the movable box 712, the movable box 712 slides downward and drives the power gear rod 714 to slide downward through the connecting slide shaft 713. When the weight inside the movable box 712 reaches a certain critical value, the power gear rod 714 contacts the inclined surface of the rebound block 716. At this time, the inclined surface of the power gear rod 714 contracts, and the power gear rod 714 loses the restriction of the connecting slide shaft 713. The power gear rod 714 slides upward under the drive of the first spring 715, thereby driving the third gear 7112 to rotate. Figure 7The second gear 717 has a retaining groove on its inner wall, and one end of the push rod 718 is extended to the inner part of the retaining groove. The collision rod 7111 is rotatably connected to the inner part of the outer frame 3. The collision rod 7111 is provided with a contact plate 7110 on its surface. The contact plate 7110 extends to the inner part of the adjacent tooth block on the surface of the second gear 717. The bell 711 is provided inside the rotation path of one end of the contact plate 7110. The rebound retaining block 716 and one end of the power gear rod 714 are both provided with inclined surfaces. The inclined surface of the rebound retaining block 716 fits with the inclined surface of the power gear rod 714, and pushes the retaining rod 718 with the surface. The second gear 717 is driven to rotate. Since the contact plate 7110 extends to the inside of the adjacent tooth block on the surface of the second gear 717, the second gear 717 rotates, thereby giving a thrust to the surface of the contact plate 7110 and the collision rod 7111 under the action of its own gravity, driving the collision rod 7111 to swing back and forth, thereby repeatedly colliding with the bell 711, thereby sending an alarm to the outside, reminding the operator to clean the dust collector in time to avoid excessive dust affecting the performance of the equipment and causing dust backflow, which helps to keep the equipment clean and operating normally, thereby extending the service life of the equipment.

[0039] The following is the entire working process and working principle of the above embodiment: when the height of the drilling drill bit 4 needs to be adjusted to meet the height requirement of the drill bit and the pipeline axis, an electric telescopic rod is provided inside the outer frame 3, which pushes the movable clamp 513 to slide through the movable rod, and then gives the two movable clamps 513 a force toward the center of the adjusting slide 511 through the central push shaft 514. When one of the two movable clamps 513 first contacts the surface of the rubber-lined pipe 2, the movable clamp 513 that first contacts the rubber-lined pipe 2 cannot slide, and thus the force is transmitted to the surface of the adjusting slide 511 by pushing the slide 512, thereby driving the adjusting slide 511 to slide in the direction of the movable clamp 513 that first contacts the rubber-lined pipe 2, until the two pushing slides are pressed. The slide plate 512 completely clamps the rubber lined pipe 2. At this time, the adjustment slide plate 511 is located at the axis of the rubber lined pipe 2. During this process, the drilling drill bit 4 is driven to slide inside the outer frame 3 through the connecting mechanism, so that the drilling drill bit 4 is aligned with the axis of the rubber lined pipe 2. This ensures that the drill bit is aligned with the axis of the pipe, which can ensure the accuracy of the hole position, reduce processing errors, and improve product quality. As the sliding plate 512 is pushed and slides toward the drilling drill bit 4 under the drive of the telescopic rod, it drives the movable gear rod 612 to slide synchronously. When the drilling drill bit 4 is aligned, the drilling drill bit 4 is driven by the telescopic rod to drill a hole in the surface of the rubber lined pipe 2. At this time, the dust collection frame 611 is in contact with the surface of the rubber lined pipe 2, and the dust drilled out is removed. As the dust outlet chute is guided to the inside of the connecting pipe 616 through the dust suction frame 611, at the same time, the sliding plate 512 is pushed to contact the inclined surface of the fixed stop block 618, thereby contracting. At this time, the movable gear rod 612 loses the limit of the movable push block 617, and slides in the direction away from the drilling drill bit 4 under the action of the spring, thereby driving the No. 1 gear 614 to rotate, and driving the fan 613 to rotate through the transmission mechanism, and the air flow flows inside the ventilation chute, thereby forming a negative pressure inside the collection box 615, thereby sucking the dust inside the connecting pipe 616 into the collection box 615 for centralized collection. Centralized dust collection can significantly reduce the dust in the working area, improve the breathing environment of the operator, and prevent dust and fine particles from entering the equipment. , resulting in equipment wear, failure or decreased accuracy. As more and more dust falls into the movable box 712, the movable box 712 slides downward and drives the power gear rod 714 to slide downward through the connecting slide shaft 713. When the weight inside the movable box 712 reaches a certain critical value, the power gear rod 714 contacts the inclined surface of the rebound block 716. At this time, the inclined surface of the power gear rod 714 contracts, and the power gear rod 714 loses the restriction of the connecting slide shaft 713. The power gear rod 714 slides upward under the drive of the No. 1 spring 715, thereby driving the No. 3 gear 7112 to rotate, and drives the No. 2 gear 717 to rotate by pushing the push rod 718 on the surface. Since the contact plate 7110 extends to the inside of the adjacent tooth block on the surface of the No. 2 gear 717,The rotation of gear number 717 causes the impact rod 7111 to swing back and forth under the action of the thrust exerted on the surface of the contact plate 7110 and the weight of the impact rod 7111 itself, thereby repeatedly colliding with the ringing bell 711. This in turn sounds an alarm, reminding the operator to clean the dust collector in a timely manner to prevent excessive dust from affecting equipment performance and causing dust backflow, helping to keep the equipment clean and operating normally, thereby extending the service life of the equipment.
